Abstract

The invention provides a wheel type slag crusher, which is used for solving the problem of the prior art that a pneumatic conveying pipeline can be blocked by massive slag. The technical scheme is that the wheel type slag crusher comprises a shell, a spindle and a bearing, wherein the upper and lower parts of the shell are respectively provided with an inlet and an outlet; an arc-shaped comb and a comb base are arranged close to the outlet; the center of the shell is provided with a bearing hole; the bearing of the spindle is arranged in the bearing hole; the slag crusher is particularly provided with a wheel plate; a hub of the wheel plate is connected to one end of the spindle so as to form an overhanging structure; the wheel edge of the wheel plate is provided with a plurality of radial round holes; slag-crushing gears are embedded in the round holes; a web of the wheel plate is bent into an annular space between the hub and the wheel edge and a central space at the centre of gravity of the wheel plate; a support ring for preventing the slag-crushing gears from running is arranged in the annular space; and the bearing hole on the center of the shell is contained in the central space. The wheel type slag crusher is designed for crushing the slag for an economizer slag crusher with small flow so as to be convenient for pneumatic conveying The wheel type slag crusher is small and light, is low-cost, and meets the demand of assembling a plurality of slag crusher for a plurality of ash discharge holes of an economizer of a coal-fired thermal power boiler.

Description

technical field [0001] The invention relates to equipment used in coal-fired thermal power plants, in particular to a wheel-type slag crusher for crushing boiler economizer ash. Background technique [0002] When the flue gas of a coal-fired thermal power boiler with a large amount of fly ash flows through the economizer of the boiler, the coarser particles and massive ash will be deposited, discharged through multiple ash outlets, and then pneumatically conveyed to the ash bin. However, these blocky ash residues are not easy to be transported by pneumatic force. Although their amount is very small, they will also block the conveying pipeline if they accumulate in small quantities. In order to solve the clogging problem of massive ash, various measures have been taken at home and abroad, but there is no good solution so far. For example, in wet slag removal, pipes are used to connect the ash outlet and the furnace bottom slag extractor, and the economizer ash is flushed i...
